Radeon R7 250 vs Radeon R9 M385X

Intro

The Radeon R7 250 makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory is set to run at a speed of 1150 MHz on this particular model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M385X, which features core clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be much faster than the Radeon R7 250 overall. (explain)

Radeon R9 M385X 96000 MB/sec
Radeon R7 250 73600 MB/sec
Difference: 22400 (30%)

Texel Rate

The Radeon R9 M385X should be a lot (about 157%) more effective at anisotropic filtering than the Radeon R7 250. (explain)

Radeon R9 M385X 61600 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 37600 (157%)

Pixel Rate

The Radeon R9 M385X is quite a bit (approximately 120%) better at full screen anti-aliasing than the Radeon R7 250, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M385X 17600 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 9600 (120%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
